We do the best job we can on the budget we have, but we cannot warrant the accuracy of these names or email addresses. We still suggest you title-address all of your postal mailings. We have sold to over 8,000 radio stations using title-addressing, so we know it works. Because the postal service allows individuals to file personal change-of-address forms, THE USE OF PERSONNEL NAMES IN A MAILING WILL VOID OUR GUARANTEE OF 99% DELIVERABILITY.

Format definition is not an exact science. Also, be aware that many program director’s perceptions of their own format is open to debate. When searching for formats, your filter should be based on CONTAINS instead of EQUALS. If you searched for all records where format equals “N/T” you would miss all the combinations of News/Talk. When a station has multiple formats, they will be listed in alphabetical order.

Market Size

For the first 260-290 markets, Nielsen Audio rankings are used. If a radio station located in one city shows up in the rating book of a larger city, its market size is listed with the larger city. If a market size ends with “.1”, this means the market size is tied with another market. Many market sizes are listed as “555.” This means the market isn’t rated. Nielsen Audio market sizes DO CHANGE. If you’ve saved a search or filter using specific size numbers, be sure to confirm that you’re getting the same markets when you re-use the filter.

A full list of markets can be found here.
